Why does this proposal have so many followers who haven't voted up questions, and who haven't offered their own questions?

Remember, you can add five example questions, to help define the site. And you can upvote five questions from other people, to help define the site. Please only upvote questions which have less than 10 votes currently: votes after the tenth don't carry any weight. Only the first ten net upvotes count.

So if you've got an upvote on a question with more than a +10 net score, you can remove that upvote by clicking again on the up button for that question, and then upvoting a different question that currently has a net score below 10.

Not really a question, but rather a call for votes.

I've just noticed a similar phenomenon on the Joomla! site proposal. Currently with 110 followers there could potentially be 55 questions with 10 votes. As it is there are just 28. 12 more questions with 10 votes are required (strange that there were only about 8 required last week?!). The site could have been in Beta long ago!?
